Arcade, Retro, Shooter
As close as you can get to fitting a late-'90s arcade in your pocket - and we're not being rude about the latest oversized Android phablet.
The Bug Butcher
Awfully Nice Studios

Space Invaders Infinity Gene
An early mobile shmup superstar, Space Invaders Infinity Gene's core evolutionary twist remains daringly fresh some seven years on.

Crescent Moon Games
Action, Arcade, Shooter
A really-quite-brilliant hardcore 2D shooter that evokes the memory of classic arcade machines, with pacy gameplay and chunky graphics. Operation Dracula most certainly does not suck.
Tesla vs Lovecraft
This twin-stick shooter packs an appealingly flamboyant steampunk style, satisfyingly squelchy gunplay, and relentless action. It's a bit of a winner.

This technically amazing dogfighting game has you swooping through the sky in your propeller-driven fighter. It's kind of like a flight sim, but one that's instantly thrilling to play.
Action, Multiplayer, Shooter
The hottest shooter sub-genre of the moment is undoubtedly Battle Royale, and PUBG is the game that kicked the craze off. Surprisingly, it works really well on mobile.

Bullet Hell Monday
Action, Arcade, Shooter
Bullet hell has rarely looked this heavenly - if your idea of heaven is a psychedelic assault of colours and shapes, that is.
Aka to Blue
Cave doesn't make mobile bullet hell shmups any more, but Aka to Blue feels like one. Besides dodging waves of bullets there's also a moreish coin-hoovering scoring system.
